Judging the weight of a curling stone is one of the most challenging aspects of being a sweeper. I’ve seen countless players struggle with this skill, even at competitive levels. After years of coaching and playing, I’ve found that one simple adjustment can make a world of difference in how accurately you assess stone speed.
The problem many sweepers face is trying to gauge the weight of a moving stone while standing still. This creates a disconnect between your perception and the actual momentum of the rock. Your static position makes it harder to feel the true speed of the stone as it travels down the ice.
A Simple But Effective Technique
Here’s my recommendation: start closer to the hack and move with the thrower as they deliver the stone. This small change transforms how you perceive the weight of the rock.
When you move alongside the thrower during delivery, several things happen:
- Your body naturally syncs with the momentum of the delivery
- You develop a physical reference point for the stone’s speed
- Your perception becomes more accurate because you’re part of the motion
- You can better anticipate whether the stone needs sweeping
This technique works because it uses your own movement as a gauge. If you’re walking briskly alongside the thrower and the stone seems to be keeping pace with you, that tells you something about its weight. If you’re moving at a moderate pace but the stone is outpacing you, that’s valuable information too.
Implementing This Approach
To put this into practice, position yourself near the hack before your teammate delivers. As they begin their delivery motion, start walking forward at a pace that matches their momentum. Pay attention to how your movement speed relates to the stone’s travel down the ice.
After several deliveries, you’ll begin to develop a feel for the relationship between:
- How fast you’re moving
- How fast the stone is traveling
- Whether the weight is heavy, light, or on target
This creates a physical memory that helps you judge future shots more accurately. Your body becomes a measuring tool for stone speed.
Why This Works Better Than Standing Still
When you stand stationary on the ice waiting for the stone to reach you, you’re forced to make split-second judgments about its speed. By the time you’ve assessed whether sweeping is needed, precious seconds have passed.
Moving with the thrower gives you continuous feedback throughout the delivery. You’re not just seeing the stone move—you’re feeling its momentum through your own motion. This kinesthetic awareness is powerful for making quick, accurate sweeping decisions.
Many top teams use this approach because it creates better communication between the thrower and sweepers. When everyone is moving together, there’s a shared understanding of the shot’s weight from the moment of release.
Practice Makes Perfect
Like any curling skill, this technique requires practice. Start implementing it during training sessions before using it in competitive play. Work with your teammates to develop consistent movement patterns that everyone understands.
The beauty of this approach is its simplicity. No special equipment or complex training is needed—just a willingness to change your positioning and movement on the ice.
Next time you’re on the ice, give this technique a try. Start closer to the hack, move with your thrower, and use your own speed to help judge the weight of the stone. I’m confident you’ll see immediate improvements in your sweeping decisions and ultimately in your team’s performance.
